send() and recv() parameters confusion

[adi.shoukat]

On server Side:
int recv (Socket,Buffer, Length, Flags)
On Client Side:
int send (Socket,Message, Length, Flags)


can anyone plz tell me weather the 1st parameter in both of above is the same thing or not??
if no .... plz tell me how to know that both the above commands are sending/receiving from same socket.
